摘要: Provided is a dongle that is connected to a portable terminal for providing a mobile banking transaction service with a banking equipment that includes a banking transaction unit for providing a mobile banking transaction service with a banking equipment; an FM transmitter for outputting a sound source played in a portable terminal through a speaker of an external FM receiver; a charger for receiving an external voltage to charge the portable terminal; and a connector to be connected to the portable terminal simultaneously or individually in order to perform functions of the banking transaction unit, the FM transmitter, and the charger. The banking transaction related components are implemented with a single separate device, i.e., dongle, and can be mounted when necessary. Therefore, a separate banking related module (software and/or hardware) is unnecessary, thereby slimming the portable terminal. In addition, the convenience of the banking transaction is improved because the dongle can be applied to general terminals having a minimum software specification.

摘要: Disclosed is a wide-band dispersion controlled optical fiber. The optical fiber enables the use of optical signals in various wavelength regions in a wavelength division multiplexing mode communication network by controlling the position of the zero dispersion wavelength, and enables long distance transmission by controlling dispersion slope and bending loss. Furthermore, there is an advantage in that the optical fiber enables not only short distance transmission but also middle/long distance transmission using a single type of optical fiber because the optical fiber is controlled to have negative dispersion values in the O-band wavelength region and positive dispersion values with small deviations in the C-band and L-band wavelength regions.

摘要: An optical fiber having a core that has a graded refractive index profile is disclosed. A clad surrounds the core and traps light within the core. A difference between differential mode delays (DMDs) at wavelengths of about 1300 nm and about 850 nm within the core is increased in a radial direction. The difference between the DMDs at both the wavelengths basically has a value equal to or less than 0.6 ns/km between a position corresponding to 50% of a radius of the core and a center of the core.
